APPATUS FOR DELIVERING GLASS 1'0- RECEPTACLIESL nace or other receptaclemay be delivered directly to a mold or other receptacle in measuredquantities, the full amount of glass required being delivered directlyfrom the furnace to the mold or other receptacle, so that all the glassdelivered to the mold is at the same temperature and no chilling of aportion of the glass has been allowed to take place before the glass isdelivered to the mold or other receptacle. This requires the cutting offof the stream of glass flowingto the mold or other receptacle from timeto time as the receptacle passes to another position and the emptyreceptacle is brought up into position to be filled.

A further object of my invention in this connection is to provide forthe cutting ofl by a quick movement of the flowing glass so thatpractically all of the time the machine is in operation, the glass isflowing directl from the furnace into themold or other receptacle, andthe time the flow is, out OK is reduced to a I A further object of myinvention is to provide for the introduction into the mold or otherreceptacle-of a substance which ;will act to insulate the molten glassfrom direct tion on the line 3-3 Fig. 2; Fig. 4 is a section on the line4-4 Fig. 2; Figs. 5 and-6 Specification of Letters Patent. 1 PafigntgdApr 111 jig 116 Application filed march 6, 1911.

are enlarged details of the receptacle for receiving the glass; Figs. 7and 8 are details of the driving mechanism and Fig. 9 is an enlargeddetail of a pipe connection to create the vacuum in the receptacle.Figs. 10 and 11 are modified forms of my invention.

In the drawings the numeral 2 designates a suitable base or platform forthe apparatus, and stepped in said base or platform .is the shaft orcolumn 3. The sleeve 4 surrounds the column 3 and secured to said sleeveis the bevel-gear '5. The bevel-gear'5 rotates on the ball-bearing 6 inthe base 2. The power-shaft 7 driven by a motor or any other suitableengine has the bevel-wheel 8 with a segmental gear or teeth '9. Theteeth 9 of the wheel 8 are adapted to engage the teeth lO'of-thebevel-gear 11 mounted on the shaft 12. A bevel-pinion 13 on the shaft 12meshes with the bevel-gear 5 on the sleeve 4.

I In this manner as more fully hereinafter .set

forth, ,an intermittent rotary movement is imparted to the sleeve 4.

Bolted or otherwise secured to the sleeve 4 is-the table 14. This tablecarries the receptacles 'or'cups 15 which are to receive the moltenglass and while I have illustrated these cups or receptacles as merelytemporary holders for the glass and from which theglass is delivered tothe mold, yet I'wish it to be understood that I do not limit my in- 4vention to receptacles of this character as the molds themselves inwhich the article is to be formed may be carried directly by the carriedby the table 14, as clearly shown in Fig. 5, This permits the cups 15 tobe tilted so as to discharge the molten glass therefrom at the propertime and in order to retain the molten glass within the cups during thetilting of same I provide for holding the glass within the cups by meansof suction and forthis purpose the cups are constructed in the followingmanner: An opening 18 is formed at'the inner end of the cup and'saidopening is partially closed by the plug 19 carried by the plate 20. Thisplate 20 engages the shoulders 21 formed in the cup and the plate isthus held at the proper distance to form a passageway 20 between theplug 19 and the walls of the opening 18. The plate 20 is held in placeby the cap 22 which is screwed into the cup. An airpassage 23 is formedin the body of the cup and said passage communicates with the interiorof the cup in the manner described through passage 20*. This passage 23communicates with the passage 24 in the trunnion 16. A bearing block 25has the tapering portion 26 which is ground to fit a correspondinglyshaped recess 27 in the trunnion and forms a bearing for the trunnion onthat side. A ground joint is provided'between the tapering portion 26 ofthe bearing-block 25 and the trunnion so as to provide against theescape of theair. The bearing-block 25 is provided with the passage 28and a pipe 29 is threaded into said block to contact with the passage28. The block 28 is held against rotation by the set-screw 30 whichpasses through the cap 31 which incloses the said bearing-block. A pipe32 is connected up with the pipe 29 and said pipe 32 in turn isconnected to the vertical pipe 33 which extends up through the cut-offplate 34. The bushing 35 extending down through the cutofl' plate 34receives the upper end ofthe pipe 33.

Securedto one of the trunnions 16 of the cup 15 is the pinion 36 whichis engaged by the pinion 37 journaled in the bearing 38. This pinion 37is engaged by the rack-bar 39 s which is'adapted to move in the guide40.

It is apparent that by the vertical movement of the rack-bar 39 the cup15 will be rotated on its trunnions as will be more fully hereinafterset forth, and I will now describe the mechanism by which this isaccomplished. The upper end of the rackbar 39 has the head 41 and duringthe rota- Y tion of the table 14 the head 41 of the rackbaris adapted tocome into engagement with the recess 42 formed in the lower end of thepiston-rod 43. This piston-rod 43 has the piston 44 which operates inthe cylinder 45. The air or other motive fiuid operating the piston 44is supplied by. the pipes 46 and 47. It is'apparent that when the piston44 is operated to move the rack-bar 39 to invert the cup 15, it willbenecessary to apply the suction to the inner end of the cup to retainthe glass in the cup during the tilting operation and this effected' inthe 'following manner: The pipe 48 connects with the pipe 46, and at itsopposite end 'said pipe connects with the sleeve 49 carried by thebracket 50 which supports the 'cylinder'45. The sleeve 49 has the outlet51 and a bypass 52 in said sleeve communicates with the bushing 53 whichis held in place by the collar .54. A coupling 55 connects the bushing53 with the passage 56 in the thimble 57 by means of the connectingcollar 58. A mouth piece 59 is connected with the thimble 57 supportedby the arm 60 secured to the effect of the walls of the and when the cuppasses to piston-rod 43. This mouth-piece 59 is adapted to coincide withv 39 so as to hold said rack-bar up in position to be engaged by thepiston-rod 43. As the cut-off plate moves around in position to bringthe head 41 of the rack-bar into engagement with the piston-rod, saidpistonrod will act to move the. star-wheel so that the tooth of saidwheel engaging the head 41 of the rack-bar'will be moved out of the wayand the further movement of the cutoff plate will act to bring anothertooth of the star-Wheel 61 into engagement with the head of the rack-barand support the same after it has passed out of engagement with thepiston-rod.

The cut-off plate 34 is bolted or otherwise secured to the sleeve 4 andmoves with the table 14. This cut-off plate is provided with theopenings62 corresponding in number to the cups 15, and in line with said cups.

molten glass so that the glass flows from the furnace into the chamber66 to be drawn off therefrom in the manner hereinafter set forth. Anysuitable receptacle, however for the'molten glass may be employed andthe glass" maintained in the proper position for flowing'in any suitablemanner.

Before'the cupsor molds come around in position to receive the moltenglass, 1 provide' for the spraying of the interior Walls of said-cupswith some substance which will act to insulate the molten glass from thewalls of the mold and so reduce the chilling mold on the glass duringthe time that the glass is being poured into the cup. Accordingly I thereservoir 67 which is carried by an arm 67 from the column 3 and saidreservoir contains the-fluid which I employ for this purpose and saidfluid may consist of .a suitable oil, soap water or any other substancewhich "may be found adapted for the purpose. A pipe 68 enters the upperend of the reservoir 66 and by means of air pressure admitted by thepipe 68, the fluid in the reservoir 66 is forced up and down through.the pipe 69 to the spraying nozzle 70,whe're the fluid is sprayed intothe cup standing in position below the nozzle. The fluid will bedirected onto the innerwalls of the cup the position beneath the pouringopening of the furnace, the molten glass in filling said cup will beinsulated from the walls of the cup to a provide a arrests certainextent by the vapor formed by the ing 62 in the cut-off plate into thecup, as

clearly indicated in Fig. 4. The cup having been previously sprayed withthe fluid from the reservoir 66, the m'olten glass as it rises withinthecup is insulated from the chilling effect of the walls ofthe'cup forthe time be ng, and as the glass flows directly from the opening in thefurnace all the glass admitted to the cup is admitted at the sametemperature so that the glass first introduced into the mold does notdiifer in consistency from that delivered later, and as a consequence isuniform in character, and that flowing in later simply falls upon a massof like consistency and temperature. This introduction of the glass inthis way prevents the formation of cords or streaks in the finishedarticle. When the proper amount of 2 glass has been introduced to thecup 15, the parts of the mechanism having been timed to operate atdetermined periods, the teeth 9 of the bevel-wheel 8 will engage withthe teeth 10 of the bevel-gear 11 and a quick rotary motion will beimparted to the sleeve 4 and to the table 14 and cut-01f plate 34. Thecut-0H plate will consequently move and in doing so the imperforateportion betweenv the'openings 62 will come in contact with the a ring'64 around the opening 65 and consequently the fiow of glass will becutoff until the next opening 62 in the cut-off plate is brought intocoincidence with the plate and another cup 15 brought into likeposition, whereupon the teeth 9will have passed from engagement with theteeth of the bevel-gear 11 and the cut-off plate and table 14 will bebrought to a standstill. The glass immediately begins to flow again intothe cup 15.. The glass first introduced into the cup comes directly fromthemolten glass in the furnace so that there is practically no chilledglass introduced to the cup which has been held back during thecessation of the flow of the glass. As a consequenc e,'as stated above,the glass first introduced mto the cup is of the same consistency asthat which fiows later into the cup and as a; consequence,

there is no liability of the imperfections inv the finished ware whichresult from glass of unequal temperatures being admitted to the mold. Atthe time that the rotation of the table 14 and cut-off plate 34 takesplace, a cup is brought around into position with reference to the moldinto which the molten glass is to be discharged and this'brings the head41 of the rack-bar into engagement with the piston rod 43. The air isadmitted to operate the piston 44 and at the same time that the air isadmitted by the pipe 46 for this purpose the air also passes downthrough the pipe 48 and through the sleeve 49 to the outlet 51. Thisadmission ofthe air by the pipe 46 not only acts tolower the piston 44.

and the rack bar 39 to tilt the cup 15 on its trunnions, but at the sametime the passage ofthe air through the pipe 48 and outlet of the sleeve49 causes a suction in the pipe mouth piece 59 through the connections.hereinbefore described and as thismouth iece 59- is directly overthebushing 35, a ike suction will be created in the pipe 32.

The connections ;of the pipe-32 with the passage 23 in the cup willcause the suction at the inner end of the cup 14an d this suction willact to hold the glass within the cup during the tilting of the same.Whenthe tilting operation has been accomplished and the tion the suctionwill be destroyed, and the contents of the cup will be discharged intothe mold to be formed by said mold into any suitable article.

In Figs. 10 and 11 I have illustrated a piston 44 is operated in theopposite direcv modified form of my invention in which the cut-off plateis not. carried by the, same rotary frame as the receptacles for theglass.

The cut-off late 75 is carried by the threaded member 6 which engagesthe sleeve 77. A bushing 78 has a web 79 which engages the recess 80 inthe member 76. A collar 81 unites the bushing and a sleeve 82 on the vstationary shaft 83. A bevel-gear 84 on sleeve 82 is engaged bybevel-gear ,85 on shaft 86. A bevel-gear 87 is engaged by the bevel-gear88. A quick rotary motion is thus given to the cut-ofi'plate 75. Thecut- T off plate may beadjusted at difl' erent heights by turning-thesleeve 77. Openings 89 are formed in the plate which are brought intocoincidence into the outlet 90 of the furnace. The openings 89 arelargerthan the outlet and so prevent contact of the glass with thesidesof said openings and so reduce the chance of the chilling of the glass,The openings 89 are elongated so thatthe glass ispermitted to flowthrough said openings before the cup 15 is brought into position toreceive the glass. Before however the glass has had time to 'drop to apoint below the upper edge of the cup said cup will have.

. moved into position to *catch and receive the glass. v

Instead of the cut-otiplate, I employ the method of cutting ofi theglass described and Y claimed in an application filed by me on the 30thday of August, 1909, Serial No. 515,271,

where the cut-oil is obtained by means of 'a suction device and in thatcase, as in the present, the lass is cut OH and held directly in theurnace or. receptacle containing the molten glass so that when thevacuum is destroyed and the glass allowed to flow the glass comesdirectly from the furnace into the mold or cup and has not beensubjected to any chilling efiect.

What I claim is:

1. In apparatus for delivering molten glass to receptacles, thecombination of a suitable rotary support, means for impartingintermittent movement to said support, a tilting receptacle on saidrotary support, a vertically movable rack-bar on said rotary support,connections between said rack-bar and said tilting receptacle, a fluidoperated piston on a stationary support, a piston-rod in the path ofsaid. rack bar and adapted to engage said rack-bar temporarily, andmeans for supporting said rack-bar. I

2. In apparatus for delivering molten glass to receptacles, thecombination of a suitable rotary support, means for imparting anintermittent movement to said support, a receptacle on said support, avertically movable rack-bar, connections between said rack-bar and saidtilting receptacle, a fluid operated piston, a piston rod in the path ofsaid rack bar and adapted to beengaged by said rack-bar temporarily, a'support adapted to support said rack-bar when disengaged from saidpiston-rod and means for throwing said support into and out of operationby said piston-rod.

3. In apparatus for delivering molten glass to receptacles, thecombination of a for throwing said star-wheel into and, out of operationby said piston-rod.

4. In apparatus for delivering molten glass to receptacles, thecombination of an intermittently operated rotary carrier, tiltablereceptacles on said carrier, a reservoir adapted to deliver to one ofsaid receptacles when said carrier is at rest, a cut-0H plate on saidcarrier, a pipe carried by said cut-oh plate, connections between saidpipe and an orifice at the inner end of said receptacle, a stationarysuction device adapted to coincide with said pipe when-the carrier is atrest at a station other than the filling station to create a suction tohold the glass within said receptacle during the tilting operation.
